and U7 drives the 3.3VLCD, Touchscreen and SD card. The ESP8266 module may be power cycled by setting Arduino digital pin D26 low (power off) then high (power on). The

nice tool for experimenting with firmware options. We preloaded your PLC with NodeMCU because we"ve found it to be the most stable and reliable code base.

The faster processor means that these touchscreens have quick operation and response times, as well as exceptional performance. Not to mention, start-up is 3 seconds from power on, so you can start working without delay.

Support multiple protocols—connects up to four PLC protocols simultaneously. Using one HMI to communicate with different brands (or manufacturers) of PLCs in a system saves time and money. The touchscreen acts as a communication gateway between multiple devices allowing data to easily pass between devices.

This state-of-the art OI Touchscreen features powerful multimedia capabilities including an SD card slot to store movie files, a built-in two video interface (2 Video In) to connect two different video cameras , audio interface (Audio Out) to connect speakers and media player to play recorded files or movie files. Applicable to 8.4” to 15” OI Touchscreen only.

FTP communication allows users to configure the HMI screen as a FTP Client or Server for transfer of programs and logged data between a Client and Server, providing a convenient and effective way to remotely communicate with the HMI.

Dynamic PLC and HMI values can be incorporated into email to show status conditions. Files, such as Alarm Log, Data Log, Operation Log and Screenshot, can be attached in the email. Up to 255 email templates can be configured to multiple recipients.

WindOI NV4 version 1.4.0 or later has a new Web Page Editor, making it simple to create professional and dynamic web pages to monitor and control an IDEC touchscreen, with no HTML programming required.

Connect a single OI Touchscreen to multiple PLCs for centralized control. One touchscreen can monitor and control each system with PLCs in several different locations.

Create an OI Touchscreen network where multiple HMIs in different locations connect to the same PLC for convenient monitoring and control. One OI Touchscreen can serve as a master, while up to 15 additional touchscreens can be slaves in the O/I Link, with a total maximum distance of 200 meters.

Conveniently download a PLC program from a PC using your OI Touchscreen. Only one cable is needed to program both units. The Pass-through function applies to IDEC (MicroSmart and OpenNet controllers) and Mitsubishi (MELSEC-FX, and Q) PLCs.

Simply set the OI Touchscreen communication protocol to the one required by your serial devices. This function uses transmit and receive instructions to build your Barcode Reader own protocol.

Communicate with two different PLC/devices at the same time. A serial or Ethernet port can be configured from our list of supported PLC manufacturers as a host, and the other serial port can be configured as a Sub Host communication with supported protocols including IDEC MicroSmart and Modbus RTU.

WindO/I-NV4 software WindO/I-NV4 software is the simplest programming tool for all IDEC OI Touchscreens Series from 4.3” to 15” except the HG1F 4.6”. The WindOI-NV4 software has the same look and feel as the WindOI NV2 with all the great features, such as support of multiple protocols, FTP and Email functions. It is used to create projects that can display information from a PLC, process status, or can be used to input data with virtual switches or keypads to make changes to a process. The objects are extremely easy to configure with the help of step-by-step navigation. It lets you quickly create colorful graphical screens in no time using drop-down menus and intuitive drag and drop functionality for the objects. A workspace is available to help you organize and manage projects, objects and screens.

Built-in Serial and Networking Protocols, this will allow IDEC Touchscreens to locally or remotely communicate with IDEC or other major brand PLC manufacturers. IDEC Touchscreen’s communications capabilities expand well beyond IDEC brand PLCs. Over 100 major PLC protocols are supported: Allen Bradley, ABB, Mitsubishi, Omron, Automation Direct (Koyo), Keyence, GE, Modicon, Siemens, Sharp, and many more.Automation Direct (Koyo), Keyence, GE, Modicon, Siemens, Sharp, and many more.

Stylish smart touch displays with an input voltage of 12-24V DC make the HG2J HMI a leading choice for applications across a variety of industries, including industrial, solar, and vehicle applications.

Whatever you are currently celebrating, Christmas, Hanukkah, Jul, Samhain, Festivus, or any other end-of-the-civil-year festivities, I wish you a good time! This December 25th edition of the Nextion Sunday Blog won"t be loaded with complex mathematical theory or hyper-efficient but difficult to understand code snippets. It"s about news and information. Please read below...After two theory-loaded blog posts about handling data array-like in strings (Strings, arrays, and the less known sp(lit)str(ing) function and Strings & arrays - continued) which you are highly recommended to read before continuing here, if you haven"t already, it"s big time to see how things work in practice! We"ll use a string variable as a lookup lookup table containing data of one single wave period and add this repeatedly to a waveform component until it"s full.A few weeks ago, I wrote this article about using a text variable as an array, either an array of strings or an array of numbers, using the covx conversion function in addition for the latter, to extract single elements with the help of the spstr function. It"s a convenient and almost a "one fits all" solution for most use cases and many of the demo projects or the sample code attached to the Nextion Sunday Blog articles made use of it, sometimes even without mentioning it explicitly since it"s almost self-explaining. Then, I got a message from a reader, writing: "... Why then didn"t you use it for the combined sine / cosine lookup table in the flicker free turbo gauge project?"105 editions of the Nextion Sunday blog in a little over two years - time to look back and forth at the same time. Was all the stuff I wrote about interesting for my readers? Is it possible at all to satisfy everybody - hobbyists, makers, and professionals - at the same time? Are people (re-)using the many many HMI demo projects and code snippets? Is anybody interested in the explanation of all the underlying basics like the algorithms for calculating square roots and trigonometric functions with Nextion"s purely integer based language? Are optimized code snippets which allow to save a few milliseconds here and there helpful to other developers?Looking through the different Nextion user groups on social networks, the Nextion user forum and a few not so official but Nextion related forums can be surprising. Sometimes, Nextion newbies ask questions or have issues although the required function is well (in a condensed manner for the experienced developer, I admit) documented on the Nextion Instruction Set page, accessible through the menu of this website. On top of that, there is for sure one of my more than 100 Sunday blog articles which deals not only with that function, but goes often even beyond the usual usage of it. Apparently, I should sometimes move away from always trying to push the limits and listen to the "back to the roots!" calls by my potential readers...Do you remember the (almost) full screen sized flicker free and ultra rapid gauge we designed in June? And this without using the built-in Gauge component? If not, it"s time to read this article first, to understand today"s improvements. The June 2022 version does its job perfectly, the needle movement is quick and smooth, and other components can be added close to the outer circle without flickering since there is no background which needs constantly to be redrawn. But there was a minor and only esthetic weak point: The needle was a 1px thin line, sometimes difficult to see. Thus, already a short time after publishing, some readers contacted me and asked if there were a way to make the needle thicker, at least 2 pixels.
